Detail

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

ImageMagick is an image display and manipulation tool for the X Window System that can read and write multiple image formats.

A flaw was found in the way ImageMagick processed images with malformed Exchangeable image file format (Exif) metadata. An attacker could create a specially-crafted image file that, when opened by a victim, would cause ImageMagick to crash or, potentially, execute arbitrary code. (CVE-2012-0247)

A denial of service flaw was found in the way ImageMagick processed images with malformed Exif metadata. An attacker could create a specially-crafted image file that, when opened by a victim, could cause ImageMagick to enter an infinite loop. (CVE-2012-0248)

It was found that ImageMagick utilities tried to load ImageMagick configuration files from the current working directory. If a user ran an ImageMagick utility in an attacker-controlled directory containing a specially-crafted ImageMagick configuration file, it could cause the utility to execute arbitrary code. (CVE-2010-4167)

An integer overflow flaw was found in the way ImageMagick processed certain Exif tags with a large components count. An attacker could create a specially-crafted image file that, when opened by a victim, could cause ImageMagick to access invalid memory and crash. (CVE-2012-0259)

A denial of service flaw was found in the way ImageMagick decoded certain JPEG images. A remote attacker could provide a JPEG image with specially-crafted sequences of RST0 up to RST7 restart markers (used to indicate the input stream to be corrupted), which once processed by ImageMagick, would cause it to consume excessive amounts of memory and CPU time. (CVE-2012-0260)

An out-of-bounds buffer read flaw was found in the way ImageMagick processed certain TIFF image files. A remote attacker could provide a TIFF image with a specially-crafted Exif IFD value (the set of tags for recording Exif-specific attribute information), which once opened by ImageMagick, would cause it to crash. (CVE-2012-1798)

Red Hat would like to thank CERT-FI for reporting CVE-2012-0259, CVE-2012-0260, and CVE-2012-1798. CERT-FI acknowledges Aleksis Kauppinen, Joonas Kuorilehto, Tuomas Parttimaa and Lasse Ylivainio of Codenomicon's CROSS project as the original reporters.

Users of ImageMagick are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All running instances of ImageMagick must be restarted for this update to take effect.

Untrusted search path vulnerability in configure.c in ImageMagick before 6.6.5-5, when MAGICKCORE_INSTALLED_SUPPORT is defined, allows local users to gain privileges via a Trojan horse configuration file in the current working directory.

It was discovered that ImageMagick would search for configuration files in the current directory. If a user were tricked into opening or processing an image in an arbitrary directory, a local attacker could execute arbitrary code with the user�s privileges.

Two security vulnerabilities related to EXIF processing were discovered in ImageMagick, a suite of programs to manipulate images: CVE-2012-0247 When parsing a maliciously crafted image with incorrect offset and count in the ResolutionUnit tag in EXIF IFD0, ImageMagick writes two bytes to an invalid address. CVE-2012-0248 Parsing a maliciously crafted image with an IFD whose all IOP tags value offsets point to the beginning of the IFD itself results in an endless loop and a denial of service.

The JPEGWarningHandler function in coders/jpeg.c in ImageMagick before 6.7.6-3 allows remote attackers to cause a denial of service (memory consumption) via a JPEG image with a crafted sequence of restart markers.

The TIFFGetEXIFProperties function in coders/tiff.c in ImageMagick before 6.7.6-3 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted EXIF IFD in a TIFF image.
